Your own experience
If you have used the battery before, you will know from your own experience as to how do they actually fare. This will help you to be aware of what to expect from the battery. There are batteries that don’t last long and their charge tends to fall down very easily. You may not find these details listed in the reviews and such knowledge comes only from experience.
This is why we would always advise you not to buy in bulk initially. When you are not sure of your buying decision, it is best advised to buy a few batteries, test them out and then you can come to the final decision regarding whether or not you should invest in them. There is absolutely no other opinion which is more reliable than your own experience. This is why choosing to try out the batteries can turn out to be an excellent solution.
Look for good deals
These days, you can find a great deal of exciting offers and discounts on almost all products. Make sure you take a thorough check on the different deals that are available. You can also buy the best batteries from sites like Amazon which often give you great discounts.
Make sure to check free shipping options. Not all brands offer free shipping and at times, you may find exciting deals on other products too. In order to shop smartly, we would advise you to run a price check on various offline and online stores and then settle for the best deal you could hope to get.
Moonrays, SunLabz, Tenergy, Urban Source and Amazon basics are five of the top brands that most people buy. Of course, this is not an exhaustive list and you can find various other local brands that may be offering you the best batteries for solar.

What are the best type of batteries for solar panels?
The best batteries for solar power off grid are those that are able to cope with the frequency in which they will be charged and discharged. This is because solar energy is sporadic – you might have no power generated one day, and then a surge of energy generated the next which means that the battery will often go through the process of being charged and discharged.
Batteries that fit into this category include:
- Lead-Acid batteries (also known as flood-cell)
- Gell cell batteries
- Absorbed Glass Mat (AGM) batteries
Lead-acid and AGM batteries are best able to cope with deep cycling. Lead-Acid batteries have frequently been put to use with solar panels and are at the cheaper end of the market. AGM batteries, while a little more expensive, have the benefit of being more robust than Lead-Acid batteries as they can be kept in any position you like (as Lead-Acid batteries need to be kept upright). Gell cell are also robust batteries, but not as good at coping with the frequency of cycles like the Lead-Acid and AGM types.
Even those these types of batteries are able to cope with charging and discharging cycles they do have their limits. You can check what this limit is by looking at the cycle life of the batteries you are considering for use with your solar panels. The number of cycles the battery is able to withstand should be included in the warranty information. Also look out for the ‘depth of discharge’ rating of the battery, so that you know how low you can allow the battery to be without charge before it is at risk of damage.
How many batteries do I need to power a house using solar energy?
It is impossible to answer this question specifically, as families have different sized homes and will use different amounts of energy. You will need to work out what the combined energy usage is for all of the appliances in your home that you are intending to power using solar energy, this will determine the size/amount of solar panels you require and the number of batteries. It is simple to work out your total energy usage via one of the energy calculators you can find on the web.
Once you have decided the number and total wattage required in your solar panels, you need to match this to your batteries. In general, the best way to do this is to match the total watt output of the solar panels to the number of amp hours on the battery. So if your solar panel measures at 60 watts, you can match this with a 60 aH battery. So, the number of batteries you need depends on the total wattage output of your solar panels.
How long can you store solar energy?
By adding a solar battery to your system this means you can store the energy you have collected from the sun, meaning you don’t need to be using up the energy you have generated immediately and it can be saved for a rainy day. But how long will it remain in your battery, say if you go through a particular gloomy winter and the sun fails to show its face?
The length of time the battery can store solar energy (if you are not using it) depends on the discharge rate. Like any battery, solar batteries do lose their charge when not in use – the rate at which this happens will depend on the battery. For example, lithium-ion batteries are good for not losing energy at a fast rate when they are not used, so are good for use if the solar energy you have generated will only be used occasionally, or if you need to rely on this energy during periods of limited sunshine.
Selecting a good quality battery for your solar energy system is an important decision. This is the part of your solar system that will store the energy that you generate so that you can use it when you need it rather than as soon as it is generated. Make sure that you choose a battery that is from a trusted brand, and has the ability to withstand frequent cycling.
Investing in solar energy is a responsible choice, one that will benefit the planet and, quite possibly your bank balance. By choosing the right solar battery you are more likely to stick with your choice to use this renewable energy source – so make sure you use our guide to ensure you get the best solar battery for your needs.
